Description

Technical Field

[0001] The invention relates to a large-scale thermal insulation facility for a tailings pond overflow well, belonging to the technical field of thermal insulation facilities for tailings pond overflow wells. Background Art

[0002] In cold regions, tailings ponds experience thick layers of ice in winter and early spring. In-use overflow wells are often located within the reservoir area and surrounded by a frozen layer, posing a safety hazard of ice loads damaging the overflow well structure. Furthermore, winter freeze-thaw cycles can adversely affect the quality of the concrete and mortar in the drainage well and the overflow well arch slab. However, due to the overflow well's unique location and structural type, there have been no reliable measures to prevent direct contact between the ice cover within the reservoir and the overflow well derrick. Therefore, the use of a tailings pond overflow well insulation shed can keep a certain area surrounding the overflow well unfrozen year-round, eliminating the safety hazard posed by the frozen layer to the overflow well structure. Summary of the Invention

The pulley group is fixed on the four corners of the top overflow well ring beam by fixing bolts. The steel wire rope passes through the pulley group. One end of the steel wire rope is wound on the winch, and the other end of the steel wire rope is connected to the roof of the insulation shed. The connector connects the winch and the floating bridge platform.

[0008] The tarpaulin is divided into two parts. One part is set outside the frame of the outer column of the insulation shed and the outer and inner oblique connecting rods of the insulation shed; the other part is set on the top of the insulation shed and extends to the outside of the frame of the outer and inner oblique connecting rods of the insulation shed.

[0009] The temperature monitoring system includes: a water level meter, a water thermometer, an indoor thermometer, an outdoor thermometer, a data acquisition instrument, a 5G network or a WIFI module, and an intelligent monitoring cloud platform; the water level meter, the water thermometer, the indoor thermometer, and the outdoor thermometer are connected to the data acquisition instrument, which is connected to the intelligent monitoring cloud platform via a 5G network or a WIFI module.

[0010] Furthermore, the winch is a manual winch or an electric winch.

[0011] Furthermore, the safety distance maintained between the diameter of the inner circle column reinforcement of the insulation shed and the overflow well arch plate is 200-300mm.

[0012] Furthermore, the height of the outer circle columns of the insulation shed is the same as the height of the overflow well arch plate.

[0013] Furthermore, the height of the outer circle columns of the insulation shed determines the size of the longitudinal space inside the insulation shed; the diameter of the tie rods of the outer circle columns of the insulation shed determines the size of the horizontal space inside the insulation shed; the number of the outer circle columns of the insulation shed and the inner circle columns of the insulation shed is determined according to the required size of the inner and outer circles of the insulation shed.

[0017] The beneficial effects of the present invention are:

[0018] The invention can keep a certain area around the overflow well in an unfrozen state all year round, eliminating the potential safety hazard caused by the frozen layer to the overflow well structure.

[0019] The present invention can keep the overflow well of the tailings pond in the cold northern region in an unfrozen state all year round within a certain area around it, eliminating the safety hazard caused by the frozen layer to the overflow well structure. In the winter and early spring seasons in the cold northern region, the outdoor temperature is usually below 0°C, and in extremely cold weather it can reach -40°C. A thick layer of ice will freeze in the water area of ​​the tailings pond, and the overflow well of the tailings pond is usually located within the water area of ​​the reservoir and surrounded by a frozen layer. When the frozen layer collapses or moves, there will be an ice load that hits the overflow well, thereby damaging the overflow well structure and posing a safety hazard. After using this invention, the temperature in the insulation shed can be controlled at 5°C or higher by adjusting the number of heating facilities that are turned on, so that the area below the water surface within the insulation shed is always in an unfrozen state, eliminating the safety hazard caused by the frozen layer to the overflow well structure.

[0020] The present invention can protect the quality of the arch slab concrete and mortar installed in the overflow well from freeze-thaw damage. Freeze-thaw cycles can cause the basic mechanical properties and deformation properties of concrete, such as compressive strength, tensile strength, and deformation characteristics, to decrease, thereby affecting the performance of the concrete structure. As an important component of the overflow well, the overflow well arch slab may deform, break, or fall off when the quality of its concrete and the mortar used to seal the arch slab is damaged, threatening the safety of the overflow well. However, the present invention can cover the installed arch slab of the overflow well in an insulation shed, protecting it from freeze-thaw damage and eliminating the safety hazards caused by freeze-thaw to the overflow well arch slab.

[0021] The present invention facilitates the installation of overflow well arch panels in winter in cold northern regions. While mortar is typically required for installation, the low outdoor temperatures in winter in cold northern regions make it difficult to install the arch panels without taking insulation measures. However, the present invention not only maintains a constant temperature above 5°C within the insulation shed, but also provides ample working space, ensuring the quality of arch panel installation in winter and facilitating winter installation.

[0022] This invention facilitates overflow well inspections in cold northern regions during winter. In northern regions, tailings ponds often freeze in winter, but the thickness of the ice varies over time. Sometimes, the thin ice prevents personnel from accessing the overflow well, making routine inspections very inconvenient. However, with this invention, personnel can freely walk on the floating bridge platform, making daily inspections more convenient. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] like Figures 1 to 9 As shown, the large-scale insulation facility for the tailings pond overflow well involved in this embodiment includes:

[0035] Example 1

[0036] The structure of large insulation facilities for tailings pond overflow well is as follows Figure 1 、 Figure 2 and Figure 4 As shown, the outer ring of the insulation shed is as follows Figure 5As shown, the outer circle of the insulation shed outer circle column reinforcement 2 is vertically provided with a number of insulation shed outer circle columns 1, and the height of the insulation shed outer circle column 1 is the height of the overflow well arch plate required for installation in winter production; the insulation shed outer circle column reinforcement 2 is connected to the insulation shed outer circle column 1, and the insulation shed outer circle and inner circle oblique connecting rods 5 are arranged at the intersection of the insulation shed outer circle column reinforcement 2 and the insulation shed outer circle column 1 top and are connected to the insulation shed inner circle column reinforcement 4 at the top, the insulation shed outer circle column and the oblique connecting rod support rod 6 are respectively connected to the insulation shed outer circle column reinforcement 2 and the insulation shed outer circle and inner circle oblique connecting rod 5, the outer circle of the insulation shed inner circle column reinforcement 4 is vertically provided with a number of insulation shed inner circle columns 3, and the insulation shed inner circle column reinforcement 4 is connected The inner circle columns 3 of the insulation shed are connected, the inner circle column reinforcements 4 of the insulation shed are arranged in the outer circle column reinforcements 2 of the insulation shed, the outer circle of the lower insulation shed and the inner circle connecting rods 7 are respectively connected to the bottom insulation shed outer circle column reinforcements 2 and the inner circle column reinforcements 4 of the insulation shed, the outer circle of the upper insulation shed and the inner circle connecting rods 8 are respectively connected to the top insulation shed outer circle column reinforcements 2 and the inner circle column reinforcements 4 of the insulation shed, the overflow well ring beam 11 is arranged in the inner circle column reinforcements 4 of the insulation shed, and the outer circle of the overflow well ring beam 11 is vertically provided with several overflow well columns 10, and the overflow well ring beam 11 is connected to the overflow well columns 10; the diameter of the inner circle column reinforcement 4 of the insulation shed is maintained at a safe distance from the overflow well arch plate, and the safety distance is 200-300mm.

[0037] The overflow well is surrounded by a floating bridge platform and a bridge assembled with plastic floats. This method is easy to install and dismantle, has a large load-bearing capacity, strong durability, and is safe and reliable. The outer circle column tie bars 2 of the bottom insulation shed, the inner circle column tie bars 4 of the insulation shed and the overflow well ring beam 11 and the outer and inner circle connecting rods 7 of the lower insulation shed are set on the floating bridge platform. Figure 6 As shown, the pulley block 12 is fixed to the four corners of the top overflow well ring beam 11 by fixing bolts 16, and the steel wire rope 13 is set through the pulley block 12. The frame size of the pulley block 12 matches the width and height of the overflow well ring beam 11. The pulley block 12 is installed on the top overflow well ring beam 11 and reinforced with bolts; a guide pulley is installed on the frame to the inside and outside of the well to form the pulley block 12. One end of the steel wire rope 13 is wound on the winch 14. The winch 14 can be a manual winch or an electric winch. The other end of the steel wire rope 13 is connected to the insulation roof 9. The connector 15 connects the winch 14 to the pontoon platform. The connector 15 can be a soft connection or a hard connection. The insulation roof 9 is set on the inner circle of the overflow well. The diameter of the insulation roof 9 is smaller than the diameter of the overflow well ring beam 11 by 100-200mm, and is separated from the overall structure of the insulation shed, as shown Figure 3 shown.

[0038] The tarpaulin is divided into two parts. One part covers the outer column 1 of the insulation shed and the outer and inner diagonal connecting rods 5 of the insulation shed. The other part covers the insulation shed roof 9 and extends (overlaps) to the outside of the insulation shed's outer and inner diagonal connecting rods 5. The tarpaulin is made of a multi-layered, quilted, waterproof material. The insulation shed roof 9 tarpaulin is cut in sections according to the cross-sectional dimensions of the overflow well frame, with enough tarpaulin left to overlap the insulation shed's inclined roof. This ensures a good seal and provides good insulation.

[0039] The temperature monitoring system includes: a water level meter, a water thermometer, an indoor thermometer, an outdoor thermometer, a data acquisition instrument, a 5G network or a WIFI module, and an intelligent monitoring cloud platform; the water level meter, the water thermometer, the indoor thermometer, and the outdoor thermometer are connected to the data acquisition instrument, which is connected to the intelligent monitoring cloud platform via a 5G network or a WIFI module.

[0040] The height of the outer circle column 1 of the insulation shed determines the size of the longitudinal space inside the insulation shed. The height of the outer circle column 1 of the insulation shed can be set to 2m; the diameter of the outer circle column tie rod 2 of the insulation shed determines the size of the horizontal space inside the insulation shed; the number of the outer circle column 1 of the insulation shed and the inner circle column 3 of the insulation shed is determined according to the required size of the inner and outer circles of the insulation shed, and the more the number, the greater the skeleton strength.

[0041] The outer circle columns 1 of the insulation shed, the outer circle column tie bars 2 of the insulation shed, the inner circle columns 3 of the insulation shed, the inner circle column tie bars 4 of the insulation shed, the outer and inner circle oblique connecting rods 5 of the insulation shed, the outer circle columns and the oblique connecting rod support rods 6 of the insulation shed, the lower outer and inner circle connecting rods 7 and the upper outer and inner circle connecting rods 8 of the insulation shed are connected by detachable plug-ins, and the plug-in parts are reinforced with bolts to form a whole, thereby increasing strength and stability.

[0042] The insulation shed uses hot air curtains for heating, which has good heating effects and is easy to operate. The submersible pump installed underwater uses a pressure water jet method to effectively prevent the water around the platform from freezing.

[0043] like Figure 8 As shown, an independent temperature monitoring system is installed in the overflow well insulation shed, including real-time temperature monitoring, i.e. indoor and outdoor temperature monitoring of the insulation shed, water temperature monitoring, and real-time water level monitoring;

[0044] Real-time water level monitoring: Overflow well water level monitoring uses the BGK-4500S piezometer, which consists of a main body with built-in vibrating wire pressure and temperature sensors and a filter (permeable stone). The standard permeable stone is made of 50-micron sintered stainless steel, which prevents fine particles from entering the sensor cavity. The BGK-4500AL is a small-range model with a range of 0.2 MPa and below, while the BGK-4500SV uses a dedicated vent cable connection to overcome the influence of atmospheric pressure on the measured value. It is suitable for water level monitoring within a range of 20 m.

[0045] How to install the water level gauge Figure 7 As shown: the water level meter, i.e., the piezometer, is connected to the reading instrument (BGK-Micro-40Pro automatic data acquisition instrument). The pressure measuring tube is set below the water surface on the outer wall of the overflow well. The automatic data acquisition instrument has built-in 5G full-network IoT network card, LAN, WIFI, and Beidou satellite interface, and can transmit monitoring data to the monitoring cloud platform through 5G (GPRS), LAN, WIFI, etc.

[0046] Water temperature monitoring: The overflow well water temperature is monitored using a BGK3700 thermometer. Figure 9 As shown, its core component uses a semiconductor thermistor sensor. The product is encapsulated in a stainless steel shell and uses a special cable, which has excellent waterproof performance.

[0047] Connect the water temperature meter to the reading instrument (BGK-Micro-40Pro automatic data acquisition instrument). The automatic data acquisition instrument has a built-in 5G full-network network card, LAN, WIFI, and Beidou satellite interface, and can transmit the measurement data to the monitoring cloud platform via 5G (GPRS), LAN, WIFI, etc.

[0048] The indoor and outdoor temperature monitoring of the insulation shed also uses the BGK3700 thermometer. The principle is the same as above. It is set indoors and outdoors of the insulation shed respectively, and the indoor thermometer and outdoor thermometer are connected to the reader (BGK-Micro-40Pro automatic data acquisition instrument). The automatic data acquisition instrument has a built-in 5G full network card, LAN, WIFI, and Beidou satellite interface. The measured indoor and outdoor temperature data can be transmitted to the monitoring cloud platform through 5G (GPRS), LAN, WIFI, etc.

[0049] The water level gauge, water temperature gauge, indoor thermometer, and outdoor temperature are connected to a readout instrument (BGK-Micro-40Pro automated data acquisition instrument). The automated data acquisition instrument has a built-in 5G network card, LAN, Wi-Fi, and Beidou satellite interfaces. This data can be transmitted to an intelligent monitoring cloud platform via 5G (GPRS), LAN, and Wi-Fi. The intelligent monitoring cloud platform allows real-time viewing of water levels, water temperatures, and indoor and outdoor temperatures. Data comparison and analysis between different devices can also be performed. By adjusting the number of heating facilities activated, the water around the overflow well remains free of ice.

[0050] Connection between devices: Depending on the on-site conditions, each device may be connected to the same data collector (one data collector can connect to 8 sensors at the same time), or some devices may be connected to a separate data collector and sent to the monitoring cloud platform via 5G or WiFi (optional depending on the on-site conditions); the monitoring cloud platform can view water level, water temperature, indoor and outdoor temperature in real time, and can also perform comparative analysis of data between different devices.

[0051] Example 2

[0052] The specific installation process of this embodiment is as follows:

[0053] Insulation shed outer ring columns 1, insulation shed outer ring column tie bars 2, insulation shed inner ring columns 3, insulation shed inner ring column tie bars 4, insulation shed outer and inner ring diagonal connecting rods 5, insulation shed outer ring columns and diagonal connecting rod support rods 6, lower insulation shed outer and inner ring connecting rods 7, upper insulation shed outer and inner ring connecting rods 8, insulation shed roof 9, overflow well columns 10, overflow well ring beam 11, pulley block 12, wire rope 13, winch 14, connector 15, fixing bolts 16, tarpaulin, pontoon platform and temperature monitoring system;

[0054] 1. Install a floating bridge platform and a bridge within a range of no less than 5m around the overflow well. Use waste tires to isolate the gap between the floating bridge platform and the overflow well arch plate to prevent the platform from hitting the overflow well arch plate and the derrick;

[0055] 2. Install the main frame of the insulation shed, including the outer circle columns 1, the outer circle column tie bars 2, the inner circle columns 3, the inner circle column tie bars 4, the outer and inner circle diagonal connecting rods 5, the outer circle columns and diagonal connecting rod support rods 6, the lower outer and inner circle connecting rods 7, and the upper outer and inner circle connecting rods 8. The above components are connected using detachable plug-ins and reinforced with bolts at the plug-in locations.

[0056] 3. Install the insulation roof 9;

[0057] 4. Install the guide pulley block 12. The installation height is the height of the existing overflow well arch plate plus the height of the tailings pond water level rise in winter. Install the guide pulley block 12 in sections around the overflow well ring beam 11 and reinforce it.

[0058] 5. Install the wire rope 13 and winch 14. Use wire rope clips to securely connect the wire rope 13 to the outer ring of the roof. Wire rope 13 is directed vertically downward in the direction of the force passing through guide pulley block 12 to connect to winch 14. Winch 14 is secured to the pontoon platform with connector 15. This ensures that when the water level in the reservoir rises, the insulation shed on the pontoon platform rises accordingly. The insulation shed roof 9 is no longer restricted by the overflow well beam, maintaining its lifting function.

[0059] 6. Lay the tarpaulin;

[0060] 7. A hot air curtain is installed in the insulation shed, and a submersible pump is installed underwater to use pressure water jet method to prevent water freezing around the platform. A large-scale insulation facility for the overflow well is integrated to ensure the inspection conditions of the overflow well in winter and avoid the hidden dangers of freezing to the overflow well.

[0061] 8. An independent temperature monitoring system is installed in the insulation shed for monitoring and surveillance. Thermometers are installed on the outside and inside of the insulation shed to monitor the outdoor ambient temperature and the indoor ambient temperature inside the shed. Liquid level gauges and water temperature monitoring facilities are installed below the water surface to monitor water level and water temperature changes. A video surveillance system is installed in the insulation shed for real-time monitoring.

[0062] The foregoing are merely preferred embodiments of the present invention. These embodiments are all different implementations based on the overall concept of the present invention. The scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention.
